perf tools: Fix parsing of pmu events with empty list of modifiers
In 1d55e8ef340d ("perf tools: Introduce opt_event_config nonterminal") I
removed the unconditional "'/' '/'" for pmu events such as
"intel_pt//" but forgot to use opt_event_config where it expected some
event_config, oops. Fix it.
Noticed when trying to use:
# perf record -e intel_pt// -a sleep 1
event syntax error: 'intel_pt//'
\___ parser error
Run 'perf list' for a list of valid events
Usage: perf record [<options>] [<command>]
or: perf record [<options>] -- <command> [<options>]
-e, --event <event> event selector. use 'perf list' to list available events
